This air purifier has been wonderful for my family. I can feel the difference when breathing. I feel like it’s more clear to breathe and I haven’t had to worry about any odors. This purifier has introduced me to a much better world. The app is easy to set up and the instructions are simple to follow. I would recommend turning on the permissions for the device. The purifier connected to my smart devices without an issue and I’ve been able to the purifier off without being in the same room. For those that like the cool LED effect, you can choose to leave the ring of light on. If you dislike it then it can easily be turned off. I think the blue light makes it look a bit more cool. The purifier isn’t too big so I haven’t had to feel like it’s an inconvenience either. It’s been amazing to have! As someone that has allergies, this has made me feel at peace.
